Weigh the fully packed parcel on a flat scale, then measure its length, width and height at the widest points of the outside. Write the numbers down in the same units the carrier asks for, because forms and labels often depend on both weight and size.
What You Need
- A scale that can hold the full parcel weight
- A rigid ruler, tape measure or folding rule
- A pen and a note card or a spreadsheet
- A flat table or counter
Weighing Steps
- Place the scale on a hard, level surface, away from vibration.
- Switch it on and wait until it shows zero. If you use a tray or bowl, place it first and then use the tare function so the display returns to zero.
- Pack the parcel completely, with tape, label and all fill in place. Weighing before you finish gives a weight that is too low.
- Set the parcel gently on the platform and let the reading settle.
- Record the number and the unit shown.
- Take the parcel off and check that the scale returns to zero. If it does not, note the difference and weigh again.
Measuring Steps
- Place the closed parcel on the table.
- Measure the longest side from edge to edge. Call this length.
- Measure the next longest side. Call this width.
- Measure the remaining side from the table to the top, including any bulge. Call this height.
- If the box bulges, measure at the widest point of the bulge, not at the corner.
- Write all three numbers in the unit the carrier asks for.
Tips for Accurate Readings
- Use the same scale and ruler each time so differences between parcels come from the parcels.
- Do not press on the parcel when you measure. Flatten a ruler against it without squeezing.
- Keep the unit consistent. Mixing centimeters with inches in the same note is a common slip.
- Re-check one in a while with a known object of fixed weight to confirm the scale still behaves.
Keeping a Simple Record
A short log saves time later. Make columns for date, order number, weight, length, width, height and the unit. When the same box and contents repeat, you can copy the earlier numbers and only confirm them with the scale. A log also helps when a carrier asks you to confirm what you entered on a form.
If numbers differ from what you expected, weigh the empty box once and then the contents on their own. The difference usually points to extra fill, tape or paperwork.
FAQ
Do I round the numbers?
Rounding rules differ. Check the carrier’s current instructions to see whether they round up and to what step.
Should I weigh before or after adding the label?
After. Labels, tape and paperwork add a little weight, and the final parcel is what the carrier measures.
The Short Version
Pack completely, weigh on a flat zeroed scale, then measure length, width and height on the outside. Record numbers and units clearly, and read the carrier’s current instructions for rounding rules.
